If you are storing these resources in the instance part of your new widget then
you do not need to use the *Hook functions.  GetValues() will just return the
data stored in the instance structure.  SetValues() will pass you a copy of the
instance structure before and after the new values have been inserted.  Take a
look at the Athena Simple Widget and Template widgets for some example source
code.
